MITER-BOX.

Application filed August 8, 1917.

J chester, Prov. of N. S., Dominion of Canada., have invented certainnew and useful mprovements in Miter-Boxes; and I do hereby declare thefollowing to be a full, clear, and exact description of the invention,such as will enable others skilled in the art to which it appertains tomake and use.

the same. i

This invention relates to miter boxes, and has particular reference toadjustable miter box structures.

The object of the invention is to provide a practical miter boxconstruction wherein a pair of swinging members move simultaneously tomeasure the same angle upon opposite sides of the line of out, so thatby a reversal of the material which is being cut, the abutting angle maybe cut with absolute accuracy.

Furthermore, the invention contemplates the provision of a' miter boXwhich is foldable into a compact relation for transportation, so that itmay be disposed in a workmans kit.

lVith the above objects in view, and such others relating` to thedetails of construction, as may hereinafter appear, my invention willnow be fully set forth and described, reference being had to theaccompanying drawings.

1n the drawings Figure 1 is a plan view,

Fig. 2 is a rear elevation,

Fig. 3 is a section on line 3-3 of Fig. 1,

Fig. 4 is a front elevation of the device,

Fig. 5 is a bottom view, and

Fig. 6 is a section on line 6-6 of Fig. 4.

Referring more particularly to the draw ings, 1 represents a base orsupport upon which the swinging tables 2 and 8 are mounted. The support1 is an elongated casting whose ends terminate in circular portions,which I term tables 4 upon which the tables 2 and 3 are pivoted by meansof the bolts 5. The outer ends of the tables 2 and 3 are provided withthe feet 6. Slide able through a transverse slot 7 formed in the middlepoint of the base or support 1, is a saw supporting bar 8, which alsoterminates at its ends in the feet 9, which together with the feet 6provide an adequate support for the entire structure. Also mountedSpecification of Letters Patent.

sel-iai No. 185,139.

upon the bolts 5, below the tables 4, are the bars 10, the latter beingsecured to the bolts 5 at intermediate points, so that arms 11 eX- tendinwardly therefrom, and the outer ends of the bars 10 are secured to thebottoms of the tables 2 and 8 by means of a bolt 12 and 13 respectively.1n order to properly support the bars 10 away from the bottoms of thetables 2 and 3 in suitable parallel and spaced relation, washers 14 areprovided upon the bolts 12 and 13.

A connecting bar or link l5 connects the tables 2 and 3, one end of thebar or link 15 being mounted upon the bolt 12, and the opposite end ofthe bar having an elongated slot 16 which rides upon the bolt 13, athumb nut 17 threaded on the bolt 13 provides a means for securing thetables in the various positions of adjustment at which the tables may beset. A series of graduations 18 upon the bar or link along the slot 16are coordinated with the various angular positions of the tables. rTheinner ends of arms 11 of the bars 10 are pivotally connected to a pairof links 19, whose opposite ends are revoluble upon a common spindle 20which eX- tends downwardly from the forward end of the bar 8. Ashereinbefore stated the bar 8 is slidable through the support 1, and byreason of the connection provided through the links 19, when the tables2 and 3 are swung with relation to the base 1, the bar is also movedwith relation to the base. The ends of the bar 8 carry the saw-guides 21and 22, said saw-guides including the slotted sleeves 23 which areslidable upon the correspondingly slotted standards 24, so that a mitersaw will be properly supported, and limited in its cut.

The tables 2 and 3 are provided with the backs or flanges 25 along therear edges, and through the flanges 25 are projected the clamping bolts26 which coperate with the stops 27 which rise from the tables, so thatmaterial may be properly fastened for the sawing operations.

1n the use of the above described instrument, it is possible to adjustthe tables for any cut within the parts indicated in Fig. 4, and thesimultaneous movement of the tables 2 and 3 by which they are always setto the same angle upon opposite sides of the line of out, makes itpossible to cut pieces for absolute it, by cutting one upon one tableand one upon another.

Aside from the above dened advantages,

it will be apparent that the device is readily folded into a compactspace so that it provides a satis'faotoryland'convenient tool for use ina carpenters kit.

Vhat I claim as my invention is i l. A miter box comprising incombination, a base plate, "saw vtables yupon the opposite ends of theb'a's'e Wplate, bolts engaged through the saw tables and the base plate,arms engaged with 4the bolts bel'ow the lbase Yplate and projectingAinwardly of the bolts, ysaid arms `bein-g anohoredto the saw tables, amember slidable through the base plate between the saw tables, linkspivoted to the inwardly vextendinfgiportons of Ethe arms-and with thesli'dable memberfnear therear'end thereof, an adjusting bar Connectedwith 4the arms Y0the opposite ends of the base plate, in'- wardlyextending arms carried by vthe saw tables, 'a 'member slidable throughthe base Vplate between thersaw tables, links connecting the free endsof the arms t0 the rear end or' the slidable member, `ran;adj-listing'bar connecting thetables, andsaw supports-Carried near -theends of-thefslidablememben In testimony whereof, I afliX my signature in thepresence foftwo witnesses.
